Entropy Production in Thermostats II [PDF]
Journal of Statistical Physics, 2007 We show that an arbitrary Anosov Gaussian thermostat close to equilibrium has positive entropy poduction unless the external field $E$ has a global potential. The configuration space is allowed to have any dimension and magnetic forces are also allowed. We also show the following non-perturbative result.

A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems
Entropy, 2022 Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

Entropy, 2014 Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.

Entropy and entropy production in some applications [PDF]
Physica A: Statistical Mechanics and its Applications, 2014 By using entropy and entropy production, we calculate the steady flux of some phenomena. The method we use is a competition method, $S_S/τ+σ={\it maximum}$, where $S_S$ is system entropy, $σ$ is entropy production and $τ$ is microscopic interaction time. System entropy is calculated from the equilibrium state by studying the flux fluctuations.

Quantifying the thermodynamic entropy budget of the land surface: is this useful? [PDF]
Earth System Dynamics, 2011 As a system is moved away from a state of thermodynamic equilibrium, spatial and temporal heterogeneity is induced. A possible methodology to assess these impacts is to examine the thermodynamic entropy budget and assess the role of entropy production ...

Machines, 2023 The existence of vortex ropes inside the draft tube significantly impacts hydraulic efficiency and operational stability, and few studies on the formation mechanism of vortex ropes and hydraulic loss problems have been explored.

Entropy, 2020 Understanding how nature drives entropy production offers novel insights regarding patient care. Whilst energy is always preserved and energy gradients irreversibly dissipate (thus producing entropy), increasing evidence suggests that they do so in the ...

Universe, 2021 Double-spiral galaxies are common in the Universe. It is known that the logarithmic double spiral is a Maximum Entropy geometry in hyperbolic (flat) spacetime that well represents an idealised spiral galaxy, with its central supermassive black hole (SMBH)

Entropy Production and the Maximum Entropy of the Universe [PDF]
The 5th International Electronic Conference on Entropy and Its Applications, 2019 The entropy of the observable universe has been calculated as Suni ~ 10104 k and is dominated by the entropy of supermassive black holes. Irreversible processes in the universe can only happen if there is an entropy gap ΔS between the entropy of the observable universe Suni and its maximum entropy Smax: ΔS = Smax − Suni.
